Improvement

Relative Date Filters in Query Builder

Date filters in the Query Builder now support relative time ranges (in addition to selecting specific calendar dates). This is especially useful for scheduled dataset exports, so each run automatically targets the most relevant time window.

Supported relative options include:

  • Last N Days
  • Last Week
  • Last Month
  • Last Quarter
  • Last Year

The backend resolves relative date selections into concrete dates at execution time, ensuring scheduled exports stay up-to-date.
